Abstract

With the development of the plastic connection technology and laser welding technology, as well as the improvement of the processing requirements of automotive plastic parts, laser transmission welding method is the first choice for the welding method of automobile plastic welding, which has the advantages of good welding quality, high efficiency and easy control. So the laser transmission welding is studied in this paper. The principle of laser transmission welding is introduced, and the transmission welding system of plastic laser is designed by using the optical fiber laser as the light source. The light beam collimation and focusing system is designed considering the divergence of the fiber laser source. The welding experiment of polypropylene specimen was carried out with the design of the optical fiber laser transmission welding system. Finally, the strength of welding specimen was tested. The results show that: the optical fiber laser transmission welding system in the laser power 40W, welding speed of 50mm/s, carbon black content of 0.1%, the welding strength is 379N, welding firm, meet the actual application needs.
